Mitochondrion a singular word for mitochondria is a "powerhouse" organelle of the cell.
<span>Mitochondrion
is an important organelle in most living organisms because it is where
biochemical processes of living organisms such as respiration takes
place. The mitochondrion has a smooth outer membrane but a larger inner
membrane. The inner membrane is about 70% protein and is very convoluted
because that can even fit inside the outer membrane. Mitochondrion is
the carrier of the Kreb's cycle in the matrix and it is responsible for
the transfer of electron chain found in the cristae of the inner
membrane.</span>
Plants use Photosynthesis for food and nutrients and produce oxygen in the progress
I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
Answer: A. Peaceful protests
Explanation:
You included no text and neither did you reference one but this should be the correct answer.
Martin Luther King Jr. was known for his non-violent style of protests that would ensure that the government would not use any violence that ensues as pretext to shutdown the protest.
In organizing peaceful protests, King made civil rights marches and the movement in general more effective because they would stage longer protests that the government would have little justification for shutting down. It also drew more empathy from people for the movement who listened to the message and not the violence.
